It depends on the installation and is typically determined by the insurance underwriters. For example, if the installation is military, which is self insured, UL/FM stickers are not usually required. If the installation is backed by a private insurer, they will typically required UL/FM approval.
When I worked in the fire industry, the requirement for UL/FM approval / stickers (or not) was always on the customers order.
